The USOC has invited representatives from the four remaining American candidates -- which also include Boston, San Francisco and Washington -- to its Colorado headquarters for what are being called low-key, informative sessions.
"We look forward to meeting with the United States Olympic Committee in Colorado Springs to discuss how we can present the strongest possible bid for our nation," Garcetti said in a statement.
The Los Angeles contingent will include the mayor, other city officials and influential businessman Casey Wasserman, multiple sources close to the meetings said. The talks were set to begin on Thursday night and continue through Friday.
The USOC has attempted to keep the preliminary stages of its process informal as a way of cutting costs for potential bidders. The committee has said it will evaluate proposals and decide at a later date whether or not to pursue a U.S. bid.
The International Olympic Committee is scheduled to select a host city in 2017.
